A LONG-SHORT, single-instrument, pure-price INTRADAY session-momentum strategy on BTCUSDT.BINANCE (USD-M perpetual), 1H bars — a deliberate FAMILY and HORIZON change away from the single-name dual-timeframe trend cluster that now fills my entire queue and lands, without exception, in the Sharpe 0.3–0.9 dead-zone that cannot clear the deflated-Sharpe gate. This is a fundamentally different mechanism: an OPENING-RANGE BREAKOUT anchored to a fixed daily reference (the US-session open, ~13:00–14:00 UTC, when crypto volume and directional follow-through are historically highest), NOT a rolling EMA/Donchian trend. Each day it defines the opening-range high/low over the first ~2 hours, then trades the CONTINUATION when price breaks that range by a fee-clearing THRESHOLD, holding intraday to session close. It runs on BTC because BTC is the only asset with demonstrated directional edge AND the deepest liquidity (so intraday breakouts have real follow-through and low slippage). This fills the under-represented short-horizon bucket (9.0% vs 10% target) and — critically — adds a DECORRELATED intraday sleeve to a book that is otherwise 100% multi-day trend, which is the diversification the portfolio actually lacks. NOT a mean-reversion fade (L53 — this trades WITH the break, not against it), NOT a volatility-compression squeeze (L54 — the trigger is a directional session break with a documented follow-through, not a low-vol pop, and the threshold is set to clear fees), NOT a rolling channel/Donchian breakout (anchored to a fixed session reference, different mechanism/regime), NOT a cross-sectional basket (L52), NOT a NON-PRICE-feed gate (the session anchor is a clock rule, 100% price otherwise — NOT L46), NOT options/COIN-M (L50/L51). To resist overfit (#1 killer, 308x): single 1H bar type, 3 parameters, fixed session window. Risk profile: ~1% equity risk/trade via a stop at the opposite side of the opening range; vol-aware sizing capped at 20% of equity*leverage; 2x leverage cap (reads self.config.leverage); ONE trade per day max (bounds fee accumulation).
